Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a moderately quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs in a bowl until well mixed.
Add the milk to the eggs and stir to combine.
Gradually pour the egg and milk mixture into the sifted flour while stirring continuously.
Strain the batter into greased gem pans.
Bake
Bake in a preheated oven at 400°F (200°C) for at least 35 minutes.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness, helping the batter set around the steam as it bakes.
- Milk
- Adds moisture, so the batter turns to steam in the oven and lifts the popovers.
- Flour
- Forms the gluten network that holds the risen shells in shape as they set.
The step that matters
Gradually pour the egg and milk mixture into the sifted flour while stirring continuously. Adding liquid slowly while stirring keeps lumps from forming, giving a smooth batter that rises evenly rather than in patches.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
